Answer:
Explanation:
The final velocity is given by the following kinematic equation:
Here, is the initial velocity, a is the body's acceleration and t is the motion time. We have to convert the time to seconds:
Now, we calculate the final velocity:
To develop the problem it is necessary to apply the concepts related to Magnetic Field.
The magnetic field is defined as
Where,
Permeability constant in free space
r = Radius
I = Current
Our values are given as,
B = 0.1T
d = 4.5mm
r = 2.25mm
If the maximum current that the wire can carry is I, then
Therefore the maximum current is 1125A
